Geomagnetic Activity Chart

NOTE: The Geomagnetic Activity Chart is created using MAGNE KA, one of ISES codes. MAGNE KA is generated based on the geomagnetic observation at Kakioka geomagnetic observatory. Moreover this chart functions as the active map linked to the table of Kakioka K indices and Data plots of geomagnetic variation at Kakioka.
